  1. Electric actuators

    Electric actuators

    Electric actuator for modulating control and on/off valves
  2. J&S Valve Metal to Metal Seated, Flange by Flange, Full Port, Series 4800

    J&S Valve Metal to Metal Seated, Flange by Flange, Full Port, Series 4800

    J&S Valve Metal to Metal Seated Control Valves can cut through solids. They are an excellent choice for use in raw sewage applications. The Full-Round Ported Metal to Metal Seated Control Valve is so strong it can cut through boards and tree limbs. The J&S Metal Seated Control Valve with it sharp tough metal seat cuts through large solids. The valve is constructed with ductile iron, fusion bonded epoxy coated with Nitronic 60 Stainless to 316 stainless seating surfaces. J&S Valve Metal Seated Control Valves are available in 3" - 108".
  3. Diaphragm Actuators

    Leslie Controls Diaphragm Actuators

    Leslie spring and diaphragm actuators are rugged high thrust units with flanged yoke to bonnet connections for simple maintenance and better access to stem packing. These workhorses of our control valve lines have been proven and perfected for nearly forty years of in-service usage. They are available in four sizes: 35, 55, 85, and 135 in.
  4. Magnum Piston Actuators/DPS Electro-Pneumatic Positioner

    Leslie Controls Magnum Piston Actuators/DPS Electro-Pneumatic Positioner

    Magnum Series piston actuators use low volume and long stroke to maximize bleed and feed rates. Externally mounted spring return modules minimize residual volume and maximize speed of response. This low volume translates into high speed of response.

    Leslie's DPS positioner, derived from Leslie's patented PMC electro-pneumatic controller technology, provides ultra-fast, stable response using a pulse modulated output and a non-mechanical, optical/digital stem position feedback.
  5. Positioners

    Leslie Controls Positioners

    The Moore 760 Series pneumatic and electro-pneumatic positioners provide cam characterization, split ranging, direct or reverse action and single or double output.

    The PMV models P5 (pneumatic) and EP5 (electro-pneumatic) positioners offer a wide variety of options due to their modular construction. These high capacity, vibration resistant units are easily mounted on both rotary or rectilinear actuators, with a variety of cams to choose from.
  6. Mallard Control Model 3200 Electric Liquid Level Controller

    Mallard Control Model 3200 Electric Liquid Level Controller

    1 1/2"-8" NPT - ANSI Class 150, 300, 600, 900, 1500, 2500 Rugged and versatile electric liquid level controller with a sealed weatherproof case and field reversible action (direct or reverse acting) ideal for offshore applications.
  7. Mallard Control Model 3200 Pneumatic Liquid Level Controller

    Mallard Control Model 3200 Pneumatic Liquid Level Controller

    Rugged and versatile pneumatic liquid level controller with a sealed weatherproof case and field reversible action (direct or reverse acting) ideal for offshore applications.
  8. Mallard Control Model 3201 Electric Liquid Level Controller

    Mallard Control Model 3201 Electric Liquid Level Controller

    1 1/2"-8" NPT - ANSI Class 150, 300, 600, 900, 1500, 2500 Electric liquid level controller with non-sealed case, primarily for onshore applications.
  9. Mallard Control Model 3201 Pneumatic Liquid Level Controller

    Mallard Control Model 3201 Pneumatic Liquid Level Controller

    1 1/2"-8" NPT - ANSI Class 150, 300, 600, 900, 1500, 2500 Pneumatic liquid level controller with non-sealed case, primarily for onshore applications.
  10. Mallard Control Model 3208-MU Threaded Hammer Union

    Mallard Control Model 3208-MU Threaded Hammer Union

    Designed to be used with the 3200/3201 liquid level controller in applications where the vessel connection is located on top of the vessel.
